摘　　要：为了有效提高轻型牵引火炮射击精度,探索了火炮回转部分质心位置变化对弹丸起始扰动的影响规律;通过调节影响火炮回转部分质心位置的总体结构变量来间接改变质心位置,并在此基础上构建了火炮回转部分质心变化与弹丸起始扰动之间的参数化有限元模型;研究结果发现火炮回转部分质心位置变化对弹丸起始扰动具有较为明显的影响,在得到回转部分质心位置变化对弹丸起始扰动影响规律的基础上,利用遗传算法对火炮回转部分质心位置进行了优化,对指导火炮总体结构设计具有一定的指导意义。In order to improve the fire accuracy of the ultra towed howitzer, the author studied the influence of initial projectile disturbances caused by the change position of the howitzer revolution＇ s centroid which is controlled by adjusting the whole structural parameters that effects the position of the howitzer revolution＇s centroid. On this base, the author built a parametric and dynamic finite element model about relationship between the change position of the howitzer revolution＇ s centroid and initial projectile disturbances. The result reveals the change position of the howitzer revolution＇ s centroid has an influence on the initial projectile disturbances. Otherwise, based on this rule that the rules of initial projectile disturbances due to the change position of the howitzer revolution＇ s centroid, the author optimized the position of the howitzer revolution＇ s centroid with the genetic algorithm. The results can provide theoretical guide for the whole structure design of the ultra towed howitzer.
